sknano.core.geometric_regions.Circle

class sknano.core.geometric_regions.Circle(center=None, r=1.0)

Geometric2DRegion for a circle.

New in version 0.3.0.

Represents the bounded region with center \((h, k)\) and radius \(r\).

Parameters:

center : array_like, optional

Center point \((h, k)\) of circle.

r : float, optional

Radius \(r\) of circle.

Notes

Calling Circle with no parameters is equivalent to Circle(center=[0, 0], r=1.0).

Attributes

area	Circle area, \(A=\pi r^2\).
center	Center point \((h, k)\) of circle.
centroid	Alias for center.
fmtstr	Format string.
measure	Alias for area, which is the measure of a 2D geometric region.
r	Circle radius, \(r\).

Methods

center_centroid()	Center centroid on origin.
contains(point)	Test region membership of point in Circle.
rotate([angle, axis, anchor_point, ...])	Rotate GeometricRegion points and vectors.
todict()	Returns a dict of the Circle constructor parameters.
translate(t[, fix_anchor_points])	Translate GeometricRegion points and vectors by Vector t.
